Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed Jannary.22, 1914. Serial No.- 813,765..

To all whom it may concern? 1 Be it known that I, MICHAEL L. Porr, a citizen of the United States, and resident of Milwaukee,in the county of Milwaukee and State of Wisconsin, have invented certain.

new and useful .I-mprovenientsjin' Oxyacetylene Apparatus';1' and I do hereby declare that the following-is a-full, clear, and exact description thereof.

MY'lIlVBIliilOIl' consists in what'is herein particularly set forth with reference to the accompanying drawings and pointed out in the 'claims of this specificatlon, its object being to provide oxyacetylene apparatus for welding and, other purposes with simple, economical andeflicient durable gas-mixing burners designed to insure such thorough mixing of the gases therein as'to'provide against crystallization of cooling metal ,at-

tacked by the ignited mixture.

Figure 1 of the drawings represents a side elevation of a "portable apparatus embody ing my invention and partly broken away,

Fig. 2, a similar view of the forward portion of the burner element of the a paratus;

Fig. 3, a like view of the rear portion of the burner illustrating the connection of pipes thereof with hose through which oxygen gas and acetylene gas are fed from valvefittings of storage-tanks, and Fig. 4, a sectional view indicated by line 4-4 in Fig. 2.

Referring by numerals to the drawings,

5 indicates the platform, 6 caster-wheels and 7 the handle of a truck. 'Mountedon the truck are standards'8 supporting a cylindrical retort 9 in which to generate oxygen gas, heat being supplied from burners 10 arranged under-the retort within asuitably disposed housing 11 and {in pipe-connection vided with a pet-cock-fitting 22, a check-- valve-fitting 23 and a cut-off valve-fitting 24. The outlet of the storage-tank is a gascontrol valve-fitting 25, and a pressure-gage 26 is also employed in connection with said storage-tank. Another storage-tank 27, containing acetylene gas under pressure, is supported on the truck and provided with a gascontrol valve-fitting 28, this fitting and the one 25 in connection with the oxygen-gas storage-tank being connected by flexible pipes in the form of suitable hose 29 and 30 to pipes 31, 32, of a burner. As a matter'of detail, each hose is slipped on a tube 33" projecting from the relative burner pipe at the rear of the same as shown in Fig. 3.

The 'burner-pipes 31 and 32 are connected by a handle-fitting 34, and said pipes'are provided with cut-off valve-fittings 35, 36, respectively. The forward ends of the burner pipes are-screw threaded in nipples 37 of a preferablyin clined hollow head 38 providing at one end with a taper-bore preferably iconicahflame-tip 39 screw-threaded inplace, and at its other end said head is provided with a screw-plug fitting 40, theplug being removable to provide foreleaning of said head and tip. The burner-pipes,

head, tip and plug are of brass or other suitable non-corrosive material, and. extending from the valve-fitting 36 through the forward portion of the pipe 32 todi'scharge within said head at a predetermined point beyondthe inletof the pipe 31 thereto, say at aboutthe inner end of the flame-tip 39,

.is 'a non-corrosive, preferably copper, tube 41 through which the oxygen-gas has its outlet to mingle with acetylene gas, the mixture being ignited at the mouth of said tip. To prevent the flame from extending back in the burner-pipe 31, the forward end of this pipe is provided with a filling 42 of rolled brass-wire or other suitable non-corrosive metal-screening.

In practice the apparatus, as a whole, is moved from place to place for welding and other operations, and there is an economy of oxygen gas by production of the same at the place of use. With particular reference to the tube 41 discharging in close proximity to the inner end of the flame-tip 39, the construction of said burner. is such as to provide for a thorough mixing of the oxygen and acetylene gases therein, and this being the case, the metal attacked by the ignited mixture Will not crystallize on cooling. Because of the hose connecting the oxygen and acetylene storage tanks with the burner, the manipulation of said burner is facilitated, and the gas-control valve-fittings 35, 36, are forward of. the handle 31. It is also to be noted that the organization of the burner is such that the flame-tip head 38 is devoid of packing-joints.

I claim:

1. In .oxyacetylene apparatus having a gas-mixing burner element comprising a non-corrosive cock-controlled pipe for valvecontrolled flexible pipe connection withan oxygen-gas storage-tank, another non-corrosive cock-controlled pipe for similar connection with an acetylene-gas storage-tank, a hollow head to whichthe cock-controlled pipes are coupled, a non-corr0sive oxygengas conveyer-tube leading from the cock of one pipe and through said pipe to discharge within the head at a predetermined point beyond the inlet thereto of the other pipe, and a flame-tip extending from said head.

- 2. Any oxyacetylene apparatus having a gas-mixing burner element comprisin a non-corrosive cock-controlled pipe for v vecontrolled flexible pipe connection with anoxygen-gas storage-tank, another non-corrosive cock-controlled pipe for similar connection with an acetylene-gas storage-tank, a conveniently arranged handle connecting the cock-controlled which said pipes are coupled, a non-corrosive oxygen-gasconveyer-tube leading from the cock of'one pipe and through said pipe acetylene-gas conveyer-pipe,

pipes, a hollow head toto discharge within the head at a predetermined point beyond the inlet thereto of the other pipe, and a flame-tip extending from said head. v

3. An oxyacetylene apparatus having a gas-mixing burner element comprising a non-corrosive cock-controlled pipe for valve one pipe and through said pipe to discharge within-the head at a predetermined point beyond the inlet thereto of the other pipe,

a flame-check in the forward end of the and a flame-tip extending from, said head.

In testimony that I claim the foregoing I have hereunto set my'hand at Milwaukee in the county ofMilwaukee andState ofWisconsin in the presence of tWo witnesses,
